getVertexLineColour()

Purpose

Find the colour (tint) of a supplied vertex line

Description

Returns a colour vector (RGBA) describing the colour of a supplied vertex line in a shape drawn with drawShape()

Syntax

colour = getVertexLineColour( shape, vertex )

Arguments

shape Handle which stores the shape in question

colour Vector (RGBA) describing the colour of the line through the supplied vertex

vertex Integer index of the desired vertex (begins at 0, clockwise)

Example

gw = gWidth()
gh = gHeight()

shape = createBox( gw / 2, gh / 2, gw / 2, gh / 2 )
coords = []
cols = []

for i = 0 to 4 loop
    col = { random( 1.0 ), random( 1.0 ), random( 1.0 ), 1 }
    setVertexColour( shape, i, col )
    coords[i] = getVertex( shape, i )
    cols[i] = getVertexLineColour( shape, i )
repeat

ink( black )
loop
    clear( bisque )
    for i = 0 to len( cols ) loop
        printAt( 0, i, "Vertex ", i, " Line Colour: ", cols[i] )
        if i == 0 or i == 3 then
            drawText( coords[i].x - 40, coords[i].y - 20, 40, black, i )
        else
            drawText( coords[i].x + 20, coords[i].y - 20, 40, black, i )         
        endif
    repeat
    drawShape( shape )
    update()
repeat
